1975-05-31 Rodolfo Martinez w rtd 7 (15) Nestor Jimenez, Campin Coliseum, Bogota, Colombia - WBC. Referee: Jay Edson. From the opening bell, Martinez got to Jimenez and punished him frequently with devastating combinations, his superiority being sustained right up until Jimenez was retired in his corner before the bell rang for the start of the eighth round. It came as no surprise as the challenger, who came out of the fight with swollen cheeks, had been badly knocked down in the seventh and had been reeling around the ring practically defenceless at the bell.
